MEANS OR APPARATUS FOR SUPPLYING LIQUID DISINFECTANTS TO THE WATER CON-TAINED IN TANKS USED FOR WATER-CLOSETS AND OTHER LIKE FLUSHING PUR-POSES.

Application filed May 12, 1928, Serial No. 277,279,. and in GreatBritain May 20, 1927.

This invention relates to improvements in means or apparatus forautomatically regulating the flow of liquid disinfectants to the watercontained in a tank or cistern or other termed and included in the termthe cistern,-employed for water closet and other like flushing purposes.

The type of apparatus to which this invention'is particularly applicableis that in which thereceptacle in which theliquid disinfectant is placedis separate from, or arranged on or in thecistern' It is preferred toattach the receptacle to and above the cistern and to provide means foran intermittent automatic supply of liquid disinfectant to the water inthe cistern. 7

In carrying this invention into practice the disinfectant receptacle maybe made in a form in which the mechanism for operating and controllingthe flow of disinfectant to the water in the cistern is arranged withinthe receptacle in which the liquid disinfectant is placed. A

In the drawings hereunto annexedz Fig. 1 a front and sectional elevationof a form of apparatus in'which the mechanism for operating andcontrolling the flow of the disinfectant is arranged within acompartment formed within the receptacle employed for containing thesaid liquid.

Like parts in all the views aremarked'with similar reference numerals. Hy p 1 is the cistern which may be made of metal or of wood linedwithsheet lead orany-other f suitable material and itis made of the usualand ordinary shape andconstruction. As illustrated in the drawings thecistern 1 is shown with an open top,but when required it may be providedwith a fixed or adjustable cover. 7 v v a r 3 is the receptacle for theliquid disinfectant. hereinafter termed disinfectant,-

and it is made in one or more portions of any suitable material thatwill not be injured the ch r'mcal act on of thedisinfectant.snitehiaftaetetiat fer recept .351;

is made of any required size and shape,-is cast or formed of sheetorother metal pressed or formed to the required shape, or it may beformed of glazed earthenware.

At the bottom 7 of each end of the receptacle is provided a lug, orflange 4' which projects in an outward direction and also is level withthe bottom of the receptacle. The lugs or flanges 4:, 4', provide meanswhereby the receptacle 3 is fixed, say, by screws 5, 5, to the uppersurface of the cistern 1. The receptacle 3 is made rectangular withvertical sides 9, 9 and ends 10, 10 and it is provided with an open topwhich is closed by a fixed 0r detachable cover 11. The bottom 7 of therece tacle 3 is made level.

In the side 9 of the disinfectant receptacle 3 is formed a verticalopening 12 which extends downwards from the open top 6 of the receptacleto or within a suitable distance I of the bottom 7 thereof, and averticalpartition 13 is provided in the interior of the receptacle 3which extends from the said top to the inner surface of the bottom 7 ofthe receptacle. The vertical partition 13 extends a suitable distancefrom the end 10 of the receptacle to beyond the opening 12 as shown at2. The vertical partition 13 is arranged parallel with the side 9 of thereceptacle 3. The space 27 between the inner surface of the verticalpartition 13 and the inner surface of the side 9 of the receptacle 3 isclosed by an end piece 14 which does not extend to the top of thevertical partition 13 and the top of the receptacle 3'Figs. 2 and 3.

By making the end piece 14 shorter in depth than the vertical partition13 a cavity is mounted upon a bolt 18,'having nuts 30,

31 on its ends,which passes through the boss 19 of-the said lever, andthe outer and free end of the horizontal arm 16 is slotted orbifurcated, for permitting of the reduced and screw threaded end 20 ofthe vertical valve rod 21 to pass through it, A nut or ployed foradjusting the position of the ver tical valve rod 21. The lower end ofthe rod 21 is reduced in size or diameter for forming a valve 22 whichis adapted to work against the seating 23 formed in a flanged boss 25formed on or fixed by a collar 25* to the upper surface of the bottom 7of the receptacle 3. A central hole M is arranged to pass through theboss 25 which is formed on the surface of the bottom of the receptaclefor the discharge of the disinfectant into the water within the cistern1.

A blcck,hereinafter termed a cam piece 26,is arranged to work in thespace 27 between the inner surface of the side 9* and verticalpartitionl3 and the cam piece is mounted on the pivot 28 and which is in the formof a spindle provided with screw'threaded ends upon which are mountedrespectively the nuts 32, 33. The cam piece 26 has a V shaped recess 26formed. in its periphery whereby a double cam is provided, one portionof which acts against the outer surface of the pendantarin 1.7 an d theother portion of the "cam is acted upon by the inclined surface of thedisc 29. The cam 26 is mounted loosely upon its pin or spindle 28 so asto enable it to act as a tripping device for intermittently acting uponthe outer surface of the arm 17 andfthe position of the V shaped opening26* is so arranged that one portion of the cam is heavier than the.other for enabling it to act as the weight for returning the cam to itsnormal position.

To the bottom 7 of the receptacle 3 is fixed a tubular pendant bearing34,Fig. 1,- which is of the same internal bore as the pipe 36 fixedwithin the float 35. The float is cylindrical in form and closed at bothof its ends which are connected centr'ally together by the pipe 36. Onthe top of the floatis fixed by soldering or other means a boss 37provided with acentral hole of the same diameter as the internal bore ofthe pipe 36 through which passes a vertical rod- 38 in which the floatis adjustably fixed by a set screw 39. The vertical rod 38 passesthrough the pipe 36 and also project's beyond the top of the float 35.To the upper end of the rod 38 is fixed the disc 29 against which theminor portion of the cam 26 acts. The disc 29. rises and falls in thespace 27ofthe receptacle 3 simultaneously with the rise and fall of thefloat 35 the movement of which is controlled by the rising and fallinglevels of the water in the cistern 1;

On the descent of the vertical rod, 38 and the float 35' which isattached thereto. as described,during or after the discharge of theflushing water has taken place,-the inclined periphery ofthe disc 29,acts upon the portion at the front of the cam 26 forraising j thevertical rod 21 and lifting the valve portion 22 of the rod clear of thevalve seating 23 for allowingthe required supply of di$- infeetant topass through the discharge opening 24 to the water in the cistern 1.

During the movement of the cam 26 the periphery of its major portionwill act upon the pendant arm 17 thereby raising the horizontal arm" 16which lifts' 'the 'rod 21. Sheet taneo'usly the float permits of the rod38 to descend with the flushing water in'the receptacle 1. During thedescent of the rod 38 and as soon as the inclined periphery of the disc29 is clear of the front portion of the cam 26 its weighted portion andthe levers 16 and '17 will return to their normal position forpermitting of the vertical rod 21 and the valve 22 to descend upon itsseating 23 for cutting off the supply of disinfectant to the water inthe cisternl; As soon as the water is again allowed to flow into thecistern 1 by means of the ordinary belltap, the float 35 will commenceto rise and by it being secured upon the rod 38, the float 35 and disc29. will all be raised simultaneously. Onthe upper surface of the disc29 coming in contact with the minor portion of the cam 26, the latterwill be raised a sufficient height to permit of the disc 29 being raisedinto the position shown at Fig; 1. During the just described trippingmotion of the cam 26 no movement of. the rod- 21 takes place until theinclined periphery of the disc 29 on'its descent again comes in contactwith the minor portion of the cam 26, as previously described.
